General description

Yu Borylation Ligand, also referred to as 2,4-dimethoxyquinoline, has been developed by Professor Jin-Quan Yu and coworkers. 2,4-dimethoxyquinoline can be prepared by reacting 2,4-dichloroquinoline with sodium methoxide.

Application

The Yu Borylation Ligand in tandem with bis(pinacolato)diboron (Aldrich 473294) under palladium catalysis can promote direct borylation of C(sp3)-H bonds. Yu and coworkers have displayed this on both alanine-derived amides and cyclopropanes with directing group assistance from the Yu-Wasa Auxiliary (Aldrich 791806).
Yu Borylation Ligand (2,4-Dimethoxyquinoline) may be used as a starting reagent in the synthesis of 2,4 -dimethoxy-3-(3methylbut-2-enyl)quinoline and 4-methoxy-1H-quinolin-2-one. It may also be used in the preparation of isoprenyl derivatives.

The Yu program centers around the discovery of catalytic carbon–carbon and carbon–heteroatom bond forming reactions based on C–H activation. Target transformations are selected to enable 1) the use of simple and abundant starting materials such as aliphatic acids, amines and alcohols, and 2) disconnections that drastically shorten the synthesis of a drug molecule or a major class of biologically active compounds.
